Plaything
OpenAL is a cross-platform 3D audio API appropriate for use with gaming applications and many other types of audio applications.
Plaything is tiny API wrapper around OpenAL, and makes it easy to play raw (PCM) streaming audio through your speakers.
Plaything was initially written to support audio playback from the spotify gem.
Note about the OpenAL bindings
Plaything contains bindings to a subset of the OpenAL API, just enough to cover the necessary streaming functionality. With little further work, the OpenAL bindings could be extracted and further developed indepdendently of Plaything.
Additionally, the OpenAL streaming source is retrievable from Plaything, and allows you to modify parameters on the playback source, such as pitch, gain, and anything else OpenAL allows you to change.
